While thiseffectively starts'the'haltspeedj.1 sheets into the folderatfull ,1 speed, it may permit the-leading: edge of" the web to rebounddue to the snap ofthe paper and thereby'losejits (register.

the longitudinal margins, or in both the transverse and longitudinal margins. These pins punch a ragged hole 35 in the three sheets of paper, turning back the torn edges of the hole through the several sheets, thereb'yforming an'efiective seal or look between vthem. This prevents the center sheet from shifting' and losing its register with the out therefore, I haveprovided for a complete registerat the front edge, between the several sheets, and have completely eliminated any tendency for variations int-hat register by rebound or other disturbances due to a tearing of the paper- 1, I 4

Although I have illustrated and described two forms of the invention, I am aware of the factthat other modifications can be made therein by any person skilled in the art without departing from the scope of the invention' as expressedijn the claims.

UTherefore, I do not wish to'be limited to the details of construction except as set forth in the claims; but what I do claim is 1'.
